check tire pressu re. Do not make a visu al judgem ent
when determ ining prop er inflation. Radial tires may look
prop erly inflated even when they are und er inflated .
Check tire pressu res more often if subject to a wide range
of outdoor tem peratu res, as tire pressu res vary with
tem peratu re changes.
Tire pressu res change by approxim ately 1 psi (7 kPa) per
12° F (7° C) of air tem peratu re change. Keep this in mind
when checking tire pressu re insid e a garage especially in
the winter.
CAUTION!

Example: If garage tem peratu re = 68° F (20° C) and the
outsid e tem peratu re = 32° F (0° C) then the cold tire
inflation pressu re shou ld be increased by 3 psi (21 kPa),
which equ als 1 psi (7 kPa) for every 12° F (7° C) for this
outsid e tem peratu re cond ition.

Inflation pressu res specified on the placard are alw ays
cold tire inflation pressu re”. Cold tire inflation pressu re
is defined as the tire pressu re after the vehicle has not
been driven for at least 3 hou rs, or driven less than 1 mile
km) after a 3 hou r period . The cold tire inflation
“
Tire pressu re may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT red uce this norm al pressu re
build up or you r tire pressu re will be too low.

pressu re must not exceed the maxim um inflation pres-
sure molded into the tire side wall.
